does anyone else find that there is a very slight overhang of the top half of the phone over the bottom layer keyboard. so that when you feel the n900 when its shut there is a slight overhang on the bottom side. i went out the other night and fell over and was wondering whether it was me who did this or whether they are all like this, the one in my local retailer had this overhang also. just wondering if yours are like this?
